Travi$ Scott and Casey Veggies' joint 'PNCXX' tour made a stop in Los Angeles last night and, among other guests, Kanye West hit the stage for a surprise, albeit brief, performance of 'New Slaves'.

Well, to label this appearance a "surprise" seems to undermine the fact that Scott and West have been working closely over the past two years or so. The Houston rapper-producer had credits on both the 'Cruel Summer' compilation and 'Yeezus,' so it's only fitting that West show the kid some love when he's in the area.

Yeezy opted to perform one of the two cuts he ran through during his 'Saturday Night Live' appearance, the visceral 'New Slaves.' While the footage shot by HHH isn't the greatest, it's not really their fault either. Once the track began playing, it seems like El Rey Theatre, the crowd, and the P.A. system exploded. In a good way.

You can watch the performance below.
